🧪 High-MW linear polymer in water, flow curve (community)

dataset id: caggioni_linear_polymer_flow

Equilibrium flow sweep of a high-molecular-weight linear polymer in aqueous solution: 51 points from 0.01 to 1000 s^-1 at 25 C. A near-ideal Carreau fluid: zero-shear plateau crossing into a power-law thinning regime. The companion oscillatory sweeps from the same TRIOS file live in caggioni_linear_polymer_amplitude_sweep and caggioni_linear_polymer_frequency_sweep (used for Cox-Merz and Delaware-Rutgers checks). Originally measured for the rheofit Carreau walkthrough.
